genes are to blame for ADHD

critic stresses the importance of the first years of life of children

Cardiff (pte/30.09.2010/10: 10) - Scientists at Cardiff University http://www.cardiff. ac.uk have direct evidence of a genetic cause of attention deficit hyperactivity disorder (ADHD) found. ADHD, the brain is directly affected as in autism. This can not be attributed to a bad education, the research team led by Anita Thapar in the journal The Lancet.

psychologist criticized Results


For the study, the DNA was analyzed from 366 children in whom the disorder was found. The clinical psychologist Oliver James, criticized the findings, however: The early years of a child are more important than the genes. In Britain alone, according to the BBC, at least two percent of children suffer from ADHD.

The researchers compared the genetic samples of ADHD children with the DNA of 1,047 healthy people. It was found that 15 percent of the ADHD group of large and rare variations in their DNA possessed. In the control group, these differences only in seven percent of the participants are identified. Thapar said that the ADHD children have a much larger number of pieces of DNA that are either double or absent. Thus, it was the first time succeeded in producing a direct genetic connection.

Scientists have taken a number of possible risk factors such as the environment. This included the education or the time before birth. It However, no evidence of an association. Some people believed that ADHD is not a real disease or just the result of bad parenting. With the study results and this stigma should again be an issue.

New treatment options in view


The researchers emphasize that not a single gene is solely responsible for ADHD. It is too early to think about the development of a test. However, now could be the biological basis of disease are clear and the creation of new treatment options.

Oliver James http://www.selfishcapitalist.com cited in his critique of studies on the Effects of anxiety in pregnant women and disturbed parent-child relationships in the first years of life. Only 57 of the 366 ADHD children had the genetic variant, which will cause the disease. This suggests that what other factors are crucial for most of the diseases. "Genes can hardly explain why some children become ill and others do not."
